Update as of Nov. 27, 2023: Matthew Alan Jock was sentenced in September to two 10-year stints of probation to run concurrently, along with two 10-year sentences suspended in the South Dakota State Penetentiary, with two days credited for time served on the charge of possession, manufacturing or distrubuting child pornography, according to county court records.

Earlier story: CANTON – A former Sioux Falls police officer pleaded guilty to two counts of child pornography Thursday morning inside a Lincoln County courtroom.

As part of the plea agreement, Matthew Alan Jock, 24, will have three of the five charges he was facing dropped. Another part of the plea agreement includes 15 years behind bars, with five years suspended. A sentencing hearing, where the state will ask for that decision, is set for Sept. 22.

According to court documents filed in February 2022, a CyberTip was received regarding a Kik Messenger account that contained video files that were suspected of depicting child pornography. Specifically, the CyberTip said the Kik Messenger account had sent several video files that depicted child pornography to other Kik Messenger users, according to court documents.

After obtaining a search warrant, investigators discovered the Kik Messenger account tied to Jock's IP address sent at least five media files depicting child pornography to other users on the platform, according to court documents.

In a post-Miranda interview, Jock admitted to using the Kik Messenger account, according to court documents.

After Jock’s arrest on Feb. 17, 2022, Sioux Falls Police Department Chief Jon Thum and Mayor Paul TenHaken appeared at a daily police briefing. Thum said then Jock was no longer part of the force.

"I am deeply troubled and quite honestly angry to learn about the allegations involving former Sioux Falls Police officer Matthew Jock," TenHaken said at the February briefing.

His arrest came just a week after ex-Sioux Falls police officer Luke Schauer, who was recently sentenced to 10 years in federal prison.
